BARREL-*H EADING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 439,241, dated October 28, 1890.

' Application fnd Marci 6, 189e.

To all whom it may concern: 1

Be it known that I, WILLIAMGLADEn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Barrel-Heading Machine, of which the following is a specification.

This invention relates to improvements in barrel-headin g machines for drawing together the spread ends of the barrel-staves, so as to confine the head of the barrel in the croze preparatory to driving on the permanent bar` In these machines as heretofore rel-hoops. constructed it has been the common practice to make one or more turns ot' a rope or cable about the ends of the staves and to tighten the rope, so as to draw the ends of the staves together, by means of a windlass or similar' This method of heading barrels apparatus. has been in use a great many years, being now the one almost universally employed in coopering, but has proven objectionable, not only because of its slowness and the loss of time necessary in properly adjusting the rope or staves, but also because of the tendency to twist the barrel out Aof shape by reason of the different planes in which the ends of the rope or cable must necessarily pass each other.

The prime object of this invention is to dispense with the employment of a rope or cable and toltighten the staves bymeans of aband engaging all of the staves in the same plane, whereby the twisting of the barrel in the tightening operation is avoided.

Another object is to dispense with the necessity for adjusting the tightening-band in position upon the barrel and to have the same of such character that it maybe readily and quickly adjusted upon and disengaged from the barrel without direct manual manipulation thereof or disconnection from the operating devices thereof, and when disengaged from the barrel will be held in convenient position for instant and ready engagement with another barrel. These objects are attained by the devices illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of a barrel-heading machine embodying my invention; Fig. 2, an enlarged detail horizontal sec 4 Serial No. 342,876. (No model.)

tion on the line 2 2 of Fig. l; Fig. 3,a top plan view of the machine, showing a barrel in position; Fig. 4, a transverse vertical section thereof on th'e line 4 4 of Fig. 3, looking in the direction indicated by the arrows; Fig. 5, a similar View on the line 5 5 of Fig. 3, and Fig. 6 a detail side elevation of the couplinglink for the tightening-band.

Similar letters of reference indicate the same parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, A indicates the supporting-frame upon which is mounted and suitably journaled in `brackets B a rocking frame O, upon which is formed apair of guides D for reception of a cross-head E, through whichl works a screw-threaded shaft F, having a common axis with the rocking frame. Power may be applied to this shaft in any suitable manner, but preferrbly by means of a cog-wheel G, mounted upon the outer end thereof, with which meshes a pinion II upon the end of a power-shaft I, journaled in suitable brackets or bearings upon the frame A of the machine and carrying atits opposite end a pair of loose friction-clutches J, driven by belts in opposite directions and operated by a lever by which the operator can readily control the direction of rotation of the screw-threaded shaft or permit the same to remain idle, as will be readily understood without detailed description, as the construction and 4operation of the clutches, and in fact theentire lnanner of securing power for the screw-threaded shaft, is immaterial and forms no part of this invention.

For the purpose of preventing cndwise movement of, or rather to take up the strain upon the screw-threaded shaft, and at the saine time reduce friction, I prefer that the end of the shaft should be socketed in a suitable bearing L, secured to the rocking frame, through which works a set-screw M, bearing against the end of the shaft, which is capable of all desirable adjustment and may be locked in any position by a lock-nut N or in any other suitable manner.

From the cross-head projects a pair of hori zontal lugs O, provided with a series of perof my machine, of any suitable character,

` K in convenient position for manipulation, t

forations P for reception of a bolt Q, to which is secured one end of an elastic steel band R, the opposite end of which is secured by a like pivoting-pin to a link S, in turn pivotally secured to a stationary lug T upon the rocking frame, and is provided witha central longitudinal slot U, (seeFig. 6,) through which works and passes the opposite end of the band-thatV is to say,`the end secured to the pin Q of the cross-head-so that all parts of the band lie in exactly the same horizontal plane without the ends having to pass by each other in different planes, as has heretofore been necessary. With the rocking frame pivoted in its bearing and a slight preponderance of weight forward of the center thereof-that is, on the side to which the tightening-band is securedit normally tends to rotate in the direction of this preponderence of weight, but is held against such rotation in such position that the band will lie in a horizontal plane by a stop V or equivalent device, but may be readily rotated in the opposite direction, carrying with it the tightening-band and elevating the latter to the inclined position shown by dotted lines in Fig. et, and, if desired, a counterbalance-weight XV may be adjustably secured to the rocking frame for the purpose of adjusting or reducing the preponderance of weight at the side of the frame, which, besides rendering the frame easier of manipulation, may also serve to assist in temporarily retaining the frame in its tilted position.

It will of course bc understood that the elastic tightening-band remains distended or approximately circular in form at all times, and that the rocking of the frame to which it is attached will cause a bodily movement of the band with the frame, between which there is maintained a fixed relation at all times, except of course as to the movements of the band in the tightening operation under the influence of the movable cross-head in contracting and expanding the band. The barrel of which the upper ends of the staves are to be drawn together by the tightening-band, so as to confine the head within the croze of 0f the staves preparatory to putting on the permanent hoop, is placed upon aplatform a, located immediately beneath the tighteningband and secured to a bracket t), adjustable upon adepending leg c from the frame of the machine by means of a bolt d, passing through the bracket and working loosely through a longitudinal slot e in said leg, whereby the platform may be vertically adjusted, according to the size of the barrel to be headed.

In the practical use of this machine the barrel is first trussed in any suitable manner and then placed in position upon the platform, the rocking frame having been previously operated so as to swing the tightening-band up out of the way, after which the end-trussed ring is removed and the tightening-band swung down over the ends of the staves. The lower trussed rings are then loosened up, so as to permit the spreading of the ends of the staves sufficiently to receive the head in the croze therein, after which the operator, by manipulating the leverK or similar power-controlling device, causes the operation of the tightening-band until the ends of all the stave-s are again drawn together in their original position with the head firmly seated, when the permanent hoop may be partially or wholly driven onto the ends of the staves and the barrel thus completed. When the operation is completed, the operator reverses the lever K, so as to cause the tightening-band to slackemwhen bymanipulating the rocking frame the band may be disengaged from the ends of the barrel and held in an elevated position ready for operation upon the next barrel.

This machine combines in the maximum degree simplicity, durability, and economy of construction, while it possesses a capacity far greater than any of the prior machines for this purpose, so far as I am aware.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

l. In a barrel-heading machine, the combination,witha flat metallic tightening-band and a pivoted link to which one end of said band is secured, said link being curved longitudinally to conform to the surface of the barrel and provided with a slot through which the other end of the band works, of a pivotal support for said band and link and means for operating said band, substantially as described.

2. In a barrel-heading machine, the combination, with a rocking frame, of a tightenin g-band carried by said f rame, a link pivoted at one end to said frame and at its opposite end to one end of said band, said link being provided with a slot through which the other end of the band works, and means for operating said band, substantially as described.

3. In a barrel-heading machine, the combination, with a rocking frame, a crosshead working and guided therein, a screw-threaded shaft Working through and actuating said head, and means for operating said shaft, of a linkpivotally secured to said frame and a tightening-band secured at its ends, respectively, to said link and cross-head, said link being provided with a slot through which works the band attached to the cross-head, substantially as described.
